METER-REGULATING DEVICE.

i Application filed February 27, 1925, Serial No. 12,187, and inSwitzerland March 8, 1924.

My invention relates to a new and improved device to adjust the positionof those elements of an electricity meter by which the speed of thedriving disk may be regulated.

The main object of the invention is to provide a device which allows aquick and exact adjustment of the said parts. I attain this object bymeans of a lever having means to engage simultaneously a stationary partof the meter and a movable part to be adjusted. for the purpose saidabove in such a manner that by moving the said lever the movable part isset to such a position as to influence the disk of the meter in thedesired manner.

In the accompanying; drawing one form of construction is shown by way ofan example.

Fig. 1 shows in a side view part of an electricity meter of. theFerraris type having a rotary disk and a brake magnet.

Fig. 2 shows the brake magnet and its support seen from above,

Figs. 3 and 4 are respectively plan view and side view 01 the settinglever.

In the drawing 1 denotes the iron core on which the current and thepressure coils are mounted in the well known manner, 2 is the diskmounted on a vertical spindle, 3 is the starting control plate, and 4 isthe braking magnet.

The starting control plate 3 is fastened to a lug 6 01 the iron core 1by means 1 a screw 5; it is provided with a hole 7. The screw 5 projectsabove the lug 6 and serves as a pivot forthe tool 8. The said tool isprovided with a bore 9 and a pin 10 near one of its ends, said bore 9being adapted to receive the screw 5 and said pin 10 being adapted toengage the opening 7 01 the plate 3. It the tool engages the screw 5 inthe stationary part 6 and, with pin 10 in the plate 3 as shown in brokenlines Fig. 1, the latter may be turned round the screw 5 to any desiredposition. The screw 5 may be loosened to facilitate the adjusting ofplate 3 and is drawn tight after the adjustment has taken place.

The brake-magnet is connected to a support 1+1 by a screw 11 and restson three screws 12 screwed into a. plate 13 which rests on the support1 1. Hence by means of the screw 11 and pins 12 the brake-magnet may beadjusted vertically with reference to the disk of the meter. The screws12 project through curved it; at sport 1 t the screw 11. is

a, or zue,

lobii revoluhle in a centre bore of the plate 13. The plate 13 isprovided with a lateral projeetion 16 having a slot 17, two edges ofwhich are parallel to each other and end at an'enlarged circular portionof slot 17.

It will be understood from the foregoing that the disc 13 rests uponsupport 1 1 and is rotatable on the screw 11, which is guided in anopening 01 the support 141 and is screwed into the magnet 4-.

The tool 8 has one of its ends bent-oft and at this bent-cit portion twopins 19 are tastened one adapted to engage the bore of stud 18 while theother pin 19 engages slot 17 between the parallel edges as shown inbroken lines (Fig. 2) By turning the tool-round the pin 19 engaging thebore in the stationary support 14 the second pin 19 abutting on one ofthe edges of slot 17 rotates the plate 13 and therewith. the brakemagnet round screw 11. The long leverage afforded by the tool 8 allowsan easy and exact adjustment.

It will be understood that primarily the magnet 1 can be rotated withthe disc 13 around the screw 11, and that the magnet can also beadjusted in its angular position with regard to the driving disc withoutinfluencing the adjustment of the magnetin regard to the position of itsslot in respect to the driving: disc 2. Moreover, the magnet can beadjusted to its height with respect to the driving disc, for instance byloosening the screws 12 and tigl'itening the screw 11, so that the slotof the magnet is positioned lower with respect to the driving disc. Alsothe screw 11 can first be loosened a little and thereupon the screws 12tightened so that the slot of the magnet is positioned. higher withrespect to the driving disc.

The shape oi the tool 8 especially the bentoii' portion with the pins 19allows the tool to turn the plate 13 a considerable range oi? movementin those meters where the ground plate is provided with side walls.

lVhat I wish to secure by U. S. Letters Patout In adjunctive mpiipmentfor adjusting the position of the brake magnet of an ll'lClHCtlOll.meter with respect to the meter disk. cooperating mounting bracket andadjusting tool means consisting 01 a plate arranged on the bracket, ascrew extending through the bracln e1; through said plate and into thebrake I magnet, and hence pivotally securing the and said plate havingmeans for the reception of members of a tool forming a lever whereby theplate and hence also the magnet 10 may be turned.

11 witness whereof I afiix my signature.
